3 Claims.

This invention relates to sights for firearms. The present applicationis a divisional of my application Serial No. 401,602, filed January 9,1941, and entitled Repeating rearm.

The aim of the present invention is to provide an improved sight forfirearms having various features of novelty and advantage and which isparticularly characterized by its simplicity and economy in constructionand arrangement, by the ease and facility with which it may be adjusted,by the readiness with which it may be swung into raised and loweredpositions, and by the security and firmness with which it is held in itsraised and adjusted position.

Other objects will be in part obvious and in part pointed out more indetail hereinafter.

The invention accordingly consists in the features of construction,combination of elements and arrangement of parts which will be exempliedin the construction hereafter set forth and the scope of the applicationof which will be indicated in the appended claims.

In the accompanying drawing:

Figure 1 is a side or edge view of my improved sight, the same beingshown in operative or raised position, and a portion of a firearm beingillustrated; and

Fig. 2 is a front elevational View of the sight, this View being takensubstantially on line 2-2 of Fig. 1 looking rearwardly in the directionof the arrows.

It is, of course, understood that my improved sight may be applied tofirearms of various constructions. In the drawing, I have shown, forillustrative purposes, a fragmentary portion of a firearm with the sightapplied thereto. The letter S designates a stock having a bore in whichis located a tube T which extends rearwardly from, or forms a part of,the receiver. The rear end of the tube is closed by a plug P. The boreof the stock may be open at the upper side of the gun so as to provide agroove IIJ above the tube.

My improved sight includes a base block I 5 located at the rear end ofthe groove IIJ of the stock and secured, as by means of a screw I6, tothe tube T adjacent the rear end thereof. The block has a forwardlyfacing shoulder I1 at each side, and forwardly of these shoulders is atransverse hole in which is located a pivot pin I8. On

the opposite projecting ends of this pin are posts I9. The openings inthe posts which receive the pin I 8 are of larger diameter than the pinso that the posts may have a limited transverse movement. The postssupport a sight-piece 20 which has a central circular portion 2|provided with a sight aperture 22. The central portion ZI is carried byside portions or arms 23 which are grooved on their opposing faces so asto provide guideways which accommodate the posts I 9. One of the postsmay be provided along its outer edge with notches 24 and one of the arms23 may have a lug 25 adapted to selectively engage in these notches inorder to hold the sightpiece in its several positions of adjustmentdepending upon the range at which the firearm is to be iired.

For the purposes of urging the posts I9 apart so that they will-frictionally engage in the opposed surfaces provided by the guidewaysof the arms 23 and for resiliently holding the sight in the elevatedposition shown in the drawing or in a down position where the sight lieshorizontally within the groove I0, catches 26 and a spring 21therebetween are provided. These catches and this spring are located ina transverse opening 28 in the base block I5 positioned above andslightly forwardly of the pivot pin I8. The catches are preferably inthe form of hollow caps having outer rounded ends so located that whenthe sight is in raised position the spring 21, acting through the caps,urges the posts I9 against the shoulder I1 of the base block. When thesight is swung to folded or down position, the catches engage the thenupper edges of the posts so as to hold the sight in that position.

In all positions of the sight, the posts are urged outwardly intofrictional engagement with the sightpiece, and the sightpiece, actingthrough the posts, hold the catches within the transverse opening 28. Itwill be observed that, due to the loose mounting of the posts on theirpivot I8, and due to the fact that the spring 21, acting through thecatches 26, tends to urge the posts apart, the sightpiece may beadjusted on the posts by pressing the free ends of the posts towardseach other, vertically adjusting the sightpiece to the desired positionand then releasing the pressure on the posts; and the sightpiece ismaintained in its adjusted position by the expanding apart of the posts.

As many changes could be made in the above construction and manyapparently widely different embodiments of this invention could be madewithout departing from the scope thereof, it is intended that all mattercontained in the above description or shown in the accompanying drawingshall be interpreted as illustrative and not in a limiting sense.

It is also to be understood that the language used in the followingclaims is intended to cover all of the generic and specific features ofthe invention herein described and all statements of the scope oftheinvention which, as a matter of language, might [be said to falltherebetween.

I claim as' my invention:

1. A sight for firearms `comprising a base having a forwardly facingshoulder at each side thereof and a transverse hole forwardly of saidshoulders, a pivot pin fitting in said hole, posts loosely mounted onthe projecting ends of said pin for swinging movement in the directionof the length of the firearm and for slight lateral movement, asightpiece slidably adjustable along said posts and having opposedsurfaces against which the outer edges of said posts are adapted toengage, and spring means urging said posts apart and in engagement withsaid surfaces to maintain said sightpiece in adjusted position.

2. A sight for firearms comprising a base having a forwardly facingshoulder to each side thereof and a transverse hole forwardly of theshoulders, a pivot pin fitting in said hole and having its endsprojecting therebeyond, posts supported on the projecting ends of saidpin for pivotal movement in the direction of the length of the firearmand for slight lateral movement, said posts engaging against saidshoulders when the sight is in elevated position, a sightpiece slidablyadjustable along said posts and and having opposed surfaces againstwhich the outer edges of said posts are adapted to engage,

and means for resiliently urging said posts apart so that they willfrictionally engage said surfaces to maintain said sightpiece inadjusted position and ffor resiliently holding the sight in its elevatedand folded positions.

3. A sight for rearms comprising a base having a forwardly facingshoulder at each side, a transverse holeforwardly of said shoulders anda transverse opening forwardly 'of and slightly above said transversehole; a pivot pin tting in said transverse hole and having its endsprojecting therebeyond, posts carried on the projecting ends of saidpins for pivotal movement in the direction of the length of the firearmand for slight lateral movement, said posts when in elevated positionhaving their rear edges engaging against said shoulders and theirforward edges intersecting the ends of said opening rearwardly of theaxis thereof and said posts when the sight is in folded position havingtheir then upper edges intersecting the ends of said opening below theaxis thereof, a sightpiece carried by said posts for vertical adjustmenttherealong and having opposed surfaces against Which the outer edges ofposts are adapted to frictionally engage, a spring within said openingfor urging said posts apart to maintain said sightpiece in adjustedposition, and catches at the opposite ends of said spring having roundedouter ends adapted to engage the inner edges of said posts.
